PRECAUTION

SDS

• Give operators access to the SDS's that apply to materials

they will be handling and ensure that they read them.

• File SDS's in an easily accessible location for immediate

reference.

• Strictly follow all the conditions in each SDS.

2.5  Environmental Safety

The following are environmental issues concerning the Gravity:
The Gravity system emits no toxic substances when using materials approved by 3D Systems.

Temperature
The optimum operating temperature range of the printer is 16-27°C (60-80°F).
Your HVAC System should have at least six air changes per hour to control the machine's waste heat.

Humidity and Altitude
Humidity should always be non-condensing and should not vary outside the range of 0% to 70% RH. Intended for indoor use

only.
The altitude limitation for proper operation of the Gravity system is up to 2000 meters / 6561.6 ft

Sound Pressure
The A-weighted sound pressure levels measured at 1 meter from the surface of the machinery and at a height of 1 meter from

the floor is as follows:
Ambient - 62.9dB Front - 68.3dB Left - 72.0dB Right - 72.6dB Rear - 70.0dB

Disposal of Gravity Material and Waste
Follow any applicable local regulations.

Emissions
Material heating - Analytical testing on 3D Systems materials indicates no detectable emissions outside acceptable limits from

the Gravity system.

2.6  Electrical Safety

Electrical Shock: Hazardous voltage exists inside the enclosures of all SLS equipment. Injury or death from

electrical shock can result if you remove external panels or try to defeat safety interlocks. Panels should only

be removed, and interlocks should only be defeated, by trained and certified 3D Systems Customer Support

personnel.
Electrical Shock: Verify your facility's electrical service ratings before connecting power to any SLS equipment.

Power must only be connected by a certified electrician.

Electrical Shock: Do not open the panel behind disconnect switch! Live voltage present. This should only be

opened by qualified personnel after power is disconnected from the facility's power circuit/breaker panel.

The Gravity equipment was designed to minimize operator exposure to electrical hazards during normal operations. All

exposed electrical circuits are inside limited-access cabinets. This is to separate the operator from service and maintenance

areas.
When operating any SLS equipment, keep the following electrical safety points in mind:
• Only 3D Systems certified service personnel should operate SLS equipment with access panels or service doors open.
